A Better Way to Fish: testing the feasibility of tunnel net ‘fish trap’ gear in North Queensland

This study found that tunnel nets are technically feasible in this location. In spite of the weather conditions, the fishing gear remained intact and successfully captured significant numbers of marketable fishes. Importantly, SOCI species were released alive and in excellent condition, as were...

Need

Much effort has been placed over the last couple of decades on the development of harvest strategies, stock assessments, risk assessments and the strategic use of ecosystem models to facilitate meeting the needs of the Commonwealth’s Harvest Strategy Policy. A focus on modelling to improve fisheries management has required effort towards method development. However, little effort has been made towards revisiting and updating the biological parameters that fundamentally underpin such modelling (e.g. growth rates, age and size at maturity, natural mortality rates, dietary information, mixing rates and stock structure) and the tools or methods used to derive them. As a result, most models now rely on parameters and community dietary data derived from information collected during the 1970s-1990s, (e.g. available maturity ogives for blue-eye trevalla are over 20 years old), or information that is borrowed from other regions or species. Whether such old or borrowed values are now representative for commercial Australian fish species is unknown but many factors point to major changes occurring in our marine environment. Australian waters in the south east and south west are climate hotspots and, overall, Australian waters have warmed faster than the global average. Key components of the productivity of marine fish (growth, maturity, and recruitment) are expected to be undergoing directional changes under a changing climate and it is entirely possible that there have been changes in fundamental productivity parameters for some Australian stocks. The reliance of current assessments on what is likely to be out-of-date information leads to increased uncertainty, which propagates into management decisions. Without an understanding of any changes in biological parameters and how any change might impact assessment frameworks, determining whether current management measures are ensuring sustainability becomes highly uncertain.

Objectives

1. Identify the origin of current biological information used in assessments of species (including empirical stock assessments and ecosystem modelling efforts) carried out under the Commonwealth Harvest Strategy Policy, including the pedigree of the information (provenance, age, appropriateness of methods used).
2. Assess the implications and risks associated with using dated and borrowed information in assessments currently used for informing fisheries management, including the scale of any risks and the species for which a change in biological parameters used in assessments has the greatest impact.
3. Identify the methods that might be applied to update priority biological parameters, including a review of the efficacy and applicability of novel methods and approaches developed in recent years.
4. Articulate a work plan including appropriate sampling regimes required for updating priority biological parameters used in assessments for those species identified as being at most at risk.

Need

Study tour participants will travel to various locations around the Gulf of Mexico to meet with Petroleum Industry members, as well as regulators. The purpose is to gain an understanding of the decommissioning landscape and regulatory environment around the Rigs-to-Reefs program, including any new policy developments. Amongst this, personnel will visit some of the offshore infrastructure in the Gulf of Mexico (GoM).

There will also be an opportunity to meet with local stakeholders, other regulators and the local seafood industry to understand their views on the Rigs-to-Reefs program and the impact on their fishing experiences. As a community organisation and regulator, this would be very insightful and provide immense value to Recfishwest and DPIRD respectively. In addition, it will have national application to the seafood industry and assist fisheries in becoming a major stakeholder in the $50B emerging Australian decommissioning industry.

Following the study tour, Recfishwest and DPIRD personnel will attend the 12th International Conference on Artificial Reefs and Related Aquatic Habitats (CARAH) in Santa Marta, Colombia. This international conference focuses on the study, development, and management of artificial reefs and aquatic habitats. These collectives typically bring together researchers, practitioners, and policymakers from around the world to share knowledge, present research findings, and discuss best practices.

These conferences aim to enhance collaboration, and attendees usually include marine biologists, ecologists, oceanographers, and representatives from non-government organisations and government agencies.

There is a great opportunity at CARAH for Recfishwest personnel to present on the outcomes of FRDC Project 2021-055 and extend upon FRDC Project 2014-005 by sharing Recfishwest’s own experiences in the artificial reef space. Sharing artificial reef knowledge from Australia will help to foster good working relationships at the international level and may contribute towards shared goals of sustainable fisheries management.

Objectives of the project include:
1. Gather knowledge and experiences of projects, assets and Rigs to Reefs policy and research outcomes in the Gulf of Mexico.
2. Meet with United States regulators to learn about the management of offshore oil and gas operations and alternative decommissioning. Identify risks to Government and marine environment from leaving decommissioned infrastructure in situ and potential mitigation measures.
3. Meet with stakeholders and end-users to get a local view on decommissioning.
4. Gather knowledge on international policy, legislative frameworks, research and management with regards to artificial reefs and aquatic habitats.
5. Share knowledge and experience from an Australian context.
6. Create a network of international artificial reef experts, including the establishment of an international artificial reef committee.
7. Bring this knowledge and these connections back to Australia to grow community and regulator capacity around artificial reefs and assist with alternative decommissioning opportunities and policy development.
